US-KMO ((ロシア語:УС-КМО)), 〔an abbreviation for Upravlyaemy Sputnik - Kontinenty Morya Okeany ((ロシア語:''Управляемый Спутник - Континенты Моря Океаны'')) meaning ''Controllable Satellite - Continents, Oceans, Seas''〕 is a series of Russian, previously Soviet, satellites which are used to identify ballistic missile launches. They provide early warning of missile attack and give information for the Moscow A-135 anti-ballistic missile system. They were run by the Russian Space Forces and its successor the Aerospace Defence Forces. These satellites are part of the Oko programme and are in geosynchronous orbit 35,750 km above the Earth's equator. This means that they are always in the same place with the same field of view. Western locations give Russia coverage of missile launches in the United States whereas more eastern ones give coverage of China and the Middle East.〔 They complement ground based early warning radars and the US-K satellites which are in molniya orbits. The first prototype satellite was launched on 8 October 1975, atop a Proton-K/DM-2 carrier rocket from Baikonur Cosmodrome. The most recent, and last of the series, was launched on 30 March 2012.〔 They are due to be replaced by the EKS series.〔〔 ==Technical information== US-KMO satellites were built by NPO Lavochkin. They feature a 1 metre diameter infrared telescope with a 4.5 metre hood which identifies missiles by their exhausts.〔 They have an operational life of 5 to 7 years, although actual performance has been variable. The satellites have the GRAU index 71Kh6. The Oko western control centre is at Serpukhov-15, Moscow Oblast 〔 although Podvig notes 〔 that satellites in the 3 eastern-most positions would be out of range of this centre, and would be controlled by the eastern control centre at Pivan-1, Khabarovsk Krai.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「US-KMO」の詳細全文を読む スポンサード リンク
